In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Fig. 1 is please referred to, Fig. 1 is the flow chart of a kind of resonance and the removing method of noise provided in an embodiment of the present invention.
The removing method of the resonance and noise is applied to the sewing machine control in linear mode control, comprising:
Step S1: the corresponding range of speeds of resonance point of sewing machine is preset；Wherein, the lower limit of the range of speeds is sewing
First revolving speed of the motor of machine, the second revolving speed that the upper limit is motor.
Specifically, the application should determine resonance point existing for sewing machine in advance, and determine corresponding to the resonance point of sewing machine
The range of speeds namely the application learn that the revolving speed of electrical motor of sewing machine specifically in which range of speeds, will lead to sewing in advance
There is resonance point in machine.Based on this, the application need to only record the upper and lower bound of the range of speeds corresponding to the resonance point of sewing machine
?.
Referring to figure 2., Fig. 2 is a kind of vibration rotation speed relation figure of a sewing machine provided in an embodiment of the present invention.Below with
For a sewing machine, illustrate that the setting process of the range of speeds corresponding to the resonance point of sewing machine includes:
It obtains first corresponding between the actual speed and the oscillation intensity of a sewing machine table of a electrical motor of sewing machine
Relationship (vibration revolving speed corresponding relationship), as shown in Fig. 2, abscissa indicates the actual speed of a electrical motor of sewing machine, ordinate is indicated
The oscillation intensity of a sewing machine table.Then being total to for a sewing machine is found out from vibration revolving speed corresponding relationship by administrative staff
Shake point, and as seen from Figure 2, the actual speed of a electrical motor of sewing machine is about between 1500rpm-1800rpm, a sewing machine
There are a resonance point, resonance point span is about 300rpm.So corresponding turn of this resonance point of a sewing machine can be set
Fast range are as follows: 1500rpm-1800rpm is specifically input to sewing machine control by the operation panel of sewing machine by administrative staff
Device, the corresponding range of speeds of resonance point to set sewing machine.
Step S2: the voltage signal of the pedal transmission of real-time reception sewing machine, and according to predeterminated voltage revolving speed corresponding relationship
Determine the rotating speed of target of the corresponding motor of voltage signal.
It should be noted that the default of the application sets in advance, it is only necessary to which setting is primary, unless according to practical feelings
Condition needs to modify, and does not otherwise need to reset.Voltage revolving speed corresponding relationship indicates the voltage signal of pedal transmission in step S2
Voltage value and electrical motor of sewing machine rotating speed of target one-to-one relationship.
Specifically, during sewing machine works, sewing machine user controls sewing by trampling the pedal of sewing machine
The actual speed (sewing velocity for determining sewing machine) of electromechanical machine, i.e., control the sewing of sewing machine by the angle of control pedal
Speed.Referring to figure 3., Fig. 3 is that motor speed and pedal angle are existing under a kind of linear mode control provided in an embodiment of the present invention
Some relation schematic diagrams.In the prior art, sewing machine is under linear mode control, the revolving speed of electrical motor of sewing machine and the angle of pedal
Directly proportional, pedal angle is bigger (it is bigger to trample degree), and the revolving speed of electrical motor of sewing machine is bigger.
In fact, pedal can be generated according to the angle of itself is corresponding when sewing machine user tramples the pedal of sewing machine
Voltage signal, and voltage signal is exported to sewing machine control.Sewing machine control can learn pedal according to voltage signal
Current angular determine the corresponding sewing machine of the current angular of pedal and according to the corresponding relationship of motor speed and pedal angle
Motor rotating speed of target (rotating speed of target refer to the motor of sewing machine be currently expected to reach revolving speed), to control sewing machine
The rotating speed of target of the actual speed real-time tracking electrical motor of sewing machine of motor realizes the control mode of Fig. 3.
Same as the prior art based on this, during sewing machine work, the application real-time reception sewing machine is stepped on
The voltage signal of plate transmission, and determine according to voltage revolving speed corresponding relationship the rotating speed of target of the corresponding motor of voltage signal, and it is existing
Unlike having in technology, the application no longer controls merely the mesh of the actual speed real-time tracking electrical motor of sewing machine of electrical motor of sewing machine
Mark revolving speed, but the corresponding range of speeds of resonance point that the actual speed of motor is avoided into sewing machine, to avoid the production of resonance point
It is raw.
Step S3: when rotating speed of target is less than the first revolving speed or is greater than the second revolving speed, the actual speed for controlling motor is real-time
Track rotating speed of target；When rotating speed of target is equal to the first revolving speed, the actual speed for controlling motor is stablized to the first revolving speed, until mesh
It marks revolving speed and is equal to the second revolving speed；When rotating speed of target is equal to the second revolving speed, the instantaneous speedup of actual speed of motor is controlled to second
Revolving speed.
Specifically, the application sets the lower limit of the corresponding range of speeds of resonance point of sewing machine as first turn of electrical motor of sewing machine
Speed, the upper limit of the range of speeds are the second revolving speed of electrical motor of sewing machine.For example, if Fig. 3 is a sewing machine under linear mode control
The relation schematic diagram of motor speed and pedal angle, then the lower limit of the corresponding range of speeds of the resonance point of a sewing machine be
1500rpm, corresponding 30 ° of pedal angle；The upper limit of the range of speeds is 1800rpm, corresponding 36 ° of pedal angle.
In order to avoid the generation of resonance point, the application is not when the rotating speed of target of electrical motor of sewing machine reaches the first revolving speed, control
The rotating speed of target of the actual speed real-time tracking electrical motor of sewing machine of machine for sewing motor.It is reached in the rotating speed of target of electrical motor of sewing machine
When the first revolving speed, the actual speed for controlling electrical motor of sewing machine is stablized to the first revolving speed, until the rotating speed of target of electrical motor of sewing machine arrives
Up to the second revolving speed.When the rotating speed of target of electrical motor of sewing machine reaches the second revolving speed, the actual speed for controlling electrical motor of sewing machine is instantaneous
Speedup is to the second revolving speed.When the rotating speed of target of electrical motor of sewing machine is greater than the second revolving speed, the actual speed of electrical motor of sewing machine is controlled
The rotating speed of target of real-time tracking electrical motor of sewing machine.
It should be noted that the corresponding range of speeds span of the resonance point of sewing machine is smaller, sewing machine user is come
It says, from during the first revolving speed instantaneous speedup to the second revolving speed, sewing machine user's makes for the actual speed of electrical motor of sewing machine
With the basic indifference of impression.
As it can be seen that the corresponding range of speeds of resonance point that the actual speed of motor is avoided sewing machine by the application, to avoid
The generation of resonance point, and then the using effect of user is improved, and extend the service life of sewing machine.
For example, the control mode according to the application improves Fig. 3, the improvement control mode of Fig. 4 can be obtained, that is, works as seam
When the angle of machine user's pedal of threading is in >=30 ° and < 36 °, the actual speed of electrical motor of sewing machine is stablized in 1500rpm；When
Sewing machine user by the angle of pedal step on 36 ° when, since the speed spans of 300rpm are smaller, instantaneous speedup can be considered as and arrived
1800rpm.Therefore, by this control mode, sewing machine is resonating when avoiding the angle of pedal between 30 ° to 36 °
Point operation.
Similarly, the yet improvement control mode of available Fig. 5: the first revolving speed is not reached in the rotating speed of target of electrical motor of sewing machine
When, control the rotating speed of target of the actual speed real-time tracking electrical motor of sewing machine of electrical motor of sewing machine.Turn in the target of electrical motor of sewing machine
When speed reaches the first revolving speed, the instantaneous speedup of actual speed of electrical motor of sewing machine is controlled to the second revolving speed, and stablize to the second revolving speed,
Until the rotating speed of target of electrical motor of sewing machine reaches the second revolving speed.The second revolving speed and later period are reached in the rotating speed of target of electrical motor of sewing machine
When greater than the second revolving speed, the rotating speed of target of the actual speed real-time tracking electrical motor of sewing machine of electrical motor of sewing machine is controlled.
In addition, the application sewing machine (is suitable for clothes in addition to working under linear mode control described in above-described embodiment
Short-movie technique), it can also work under nonlinear Control mode and (be suitable for the techniques such as seam lengthy motion picture such as curtain gauze).Please refer to figure
6, Fig. 6 be the acceleration graph of motor speed under a kind of nonlinear Control mode provided in an embodiment of the present invention, i.e. sewing machine makes
User steps on pedal maximum angle and within a certain period of time by the stabilization of speed of electrical motor of sewing machine under maximum speed in moment
Work.The time of usual T1 is very small, within 1-2s, so time of the sewing machine in accelerator in resonance point is very
It is few, it within ms, can be ignored, without being improved to nonlinear Control mode.
The present invention provides the removing methods of a kind of resonance and noise, applied to the sewing machine control for being in linear mode control
Device processed, comprising: preset the corresponding range of speeds of resonance point of sewing machine；Wherein, the lower limit of the range of speeds is sewing machine
